A microcontroller (10) is adapted, when operating, to execute programs and instructions and, in response, to generate control signals to selectively control external apparatus. The microcontroller (10) includes a power supply (70, 85) for supplying power to the overall device within a predetermined range suitable for its operation, and a clock for supplying a clock frequency to the microcontroller with a stability suitable for precise timing and counting within the device. The microcontroller (10) is selectively reset to prevent it from executing programs and instructions for purposes of generating the control signals, and is maintained in the reset condition despite initiation of a removal from the reset condition, until the power supplied by the power supply (70, 85) is in a predetermined range and the clock frequency supplied by the clock is stable. |
